Any attempt to bypass it failed. I'm sorry if I'm creating even more noise.
Brief summary of the problem:
When launching a game like Counter-Strike 2 or OpenRA there is a chance of 10% - 20 % that the backlight turns off. The only workaround I'm aware to get it on again is a suspend and resume i.e. Fn+4 and Fn.

- Type of Display Connection: eDP
System information:
- Distro name and Version: Archlinux
- Kernel version:
6.5.9(# edit: 6.6.8, still happening)
How to reproduce the issue:
- Launch a game which causes some kind of workload on the GPU
